sealer/gasket question...

[97snk]

What gasket should the sealer be used on overall and does it go on the whole gasket or just parts where the flow occurs...I finally got everything cleaned up and going to start putting this motor back together tomorrow...

Thanks in advance...

What part of the engine? Typically blue RTV is a good choice for things like timing chain covers and water pumps and other low temp parts. You want to apply a very thin coat to any surface that is containing a fluid. Or just follow the elastomer bead that the factory gasket has. Or just put it where you had to clean it off the part you just removed.

Yea, I knew it went on the timing cover gasket, wasn't sure about water pump gasket and the thermostat gasket...

I actually use the gray sealant from Right Stuff. It is very versatile and dries quick. You can actually put it in use within 10-15min after application. It is OEM approved for most imports. It is higher temp than blue rtv and can reliably replace a gasket if necessary.
The oil pan gasket on rotary engines are notorious for leaking because of the varying expansion rates of the plates. Many of the new engine builders will use only Right Stuff to seal the pan, sans gasket, and never worry about leaks again.
I have been using it for about 5yrs now and everything from front covers to water pumps, and never had one hint of seepage or leaking.
I'm going to use it on my timing cover and rear cover and t-stat gaskets, and have seriously thought of not even using a gasket and only putting the Right Stuff on and seeing how it works. But the rear cover and front cover a PITA to get to and check for seepage or fix if it did leak, so I haven't decided yet.

here is from the Permatex info:
The Right Stuff Grey Gasket Maker was specifically designed to perform under the higher torque loads caused by engines with closely spaced bolt patterns (typically import vehicles, particularly Japanese). It is is blowout resistant, allowing leakproof gaskets to be made and put into service in just one minute. Sensor-safe, this product seals instantly, forming a reliable, long lasting elastomeric rubber gasket that outperforms precut gaskets. OEM specified by Honda, Nissan and Mazda. This product is resistant to powertrain fluids (oil, coolant, and ATF) and operates in environments to 450°F (232°C) continuous; 500°F (260°C) intermittent.

Bottlefed beat me to it, I've turned a wrench professionally for 20 years and by far the best sealant in the world is right stuff!!!!! I would almost use this **** for a head gasket, it has saved my ass more times than I can count and I can tell you, if right stuff doesn't seal it, NOTHING WILL!!!!! DONT!! use that other crap that the auto stores sell, right stuff comes in either a cheez **** type can, or in a caulk tube with a gun. It's expensive, but its worth its weight in gold! It is the only sealant allowed in my shop. Just my 2c. Mark, ASE L1 CDMAT

I did some search on the right stuff, most people complain about it drying it up really quick. Who carries this stuff? I can't seem to find any sale links besides amazon...

Edit:

Found it...you can buy it at...

Ace Hardware Stores
Do-It-Best
True Value Hardware Stores
Lowes
Family Dollar
Dollar General
Blain's Farm & Fleet

I buy it at autozone or o'reilly autoparts stores. I believe napa sells it as well.

It does dry up in the container within 3-6 months after opening it, depending on how you store it. But most sealant manufacturers recommend using their products within that period as well.

Thanks for the help guys...

This is by far the best silicone sealant I have ever used, been using this stuff for engines for decades now. I buy it from a local International Navistar Truck service station where they service big rigs. It's expensive, around $60 or so.. but it's used on transport truck engines that run millions of miles. The color of the silicone is grey which I prefer also. An International mechanic told me that they only use this silicone on the oil pan without a gasket. Once it cures, it's extremely flexible rubber and has incredible adhesion and doesn't dry as quick as Right Stuff.

If you're not already hooked on Right Stuff (which is good too), for anyone who rebuilds engines, do yourself a favor and buy a tube of this silicone you'll thank me one day.. International part number is 1830856C1, or as Wacker A 442 if you can find another place that sells it (maybe a Ford dealership that services Powerstroke / Navistar International truck engines).
